Practice Questions
Question 1 | Section: QT and DI | ID: 100003
The table given below represents the number of cars sold by four dealers P, Q, R and S in six months of a given year. Based on the given data, answer the question.
The total number of cars sold by dealer Q in April, May and June is what percent of the total number of cars sold by all dealers in February and April?
| Dealers | P | Q | R | S | Total |
|---|---|---|---|---|---|
| January | 102 | 92 | 95 | 107 | 396 |
| February | 94 | 96 | 104 | 106 | 400 |
| March | 85 | 94 | 100 | 90 | 369 |
| April | 108 | 97 | 99 | 96 | 400 |
| May | 98 | 102 | 100 | 89 | 389 |
| June | 95 | 108 | 102 | 91 | 396 |
Correct Option: 38 3/8
Solution:
Total cars sold by dealer Q in April, May, and June:
April: 97 | May: 102 | June: 108
Total Q = 97 + 102 + 108 = 307
Total cars sold by all dealers in February and April:
Total February: 400 | Total April: 400
Total All = 400 + 400 = 800
Percentage = (307 / 800) * 100 = 307 / 8 = 38.375%
Converting 0.375 to a fraction: 375/1000 = 3/8. So, 38 3/8 %
Rationale: Summed specific months for Q and compared to combined totals of Feb/Apr.
Difficulty: Easy
Solution:
Total cars sold by dealer Q in April, May, and June:
April: 97 | May: 102 | June: 108
Total Q = 97 + 102 + 108 = 307
Total cars sold by all dealers in February and April:
Total February: 400 | Total April: 400
Total All = 400 + 400 = 800
Percentage = (307 / 800) * 100 = 307 / 8 = 38.375%
Converting 0.375 to a fraction: 375/1000 = 3/8. So, 38 3/8 %
Rationale: Summed specific months for Q and compared to combined totals of Feb/Apr.
Difficulty: Easy
Question 2 | Section: QT and DI | ID: 100002
The table given below represents the number of cars sold by four dealers P, Q, R and S in six months of a given year. Based on the given data, answer the question.
What is the ratio of the total number of cars sold by dealer P in February, April and May to the total number of cars sold by dealer S in March, May and June?
| Dealers | P | Q | R | S | Total |
|---|---|---|---|---|---|
| January | 102 | 92 | 95 | 107 | 396 |
| February | 94 | 96 | 104 | 106 | 400 |
| March | 85 | 94 | 100 | 90 | 369 |
| April | 108 | 97 | 99 | 96 | 400 |
| May | 98 | 102 | 100 | 89 | 389 |
| June | 95 | 108 | 102 | 91 | 396 |
Correct Option: 10:9
Solution:
Total P (Feb, Apr, May) = 94 + 108 + 98 = 300
Total S (Mar, May, June) = 90 + 89 + 91 = 270
Ratio = 300 : 270 = 10 : 9
Rationale: Summed sales for specified months and simplified the ratio by 30.
Difficulty: Easy
Solution:
Total P (Feb, Apr, May) = 94 + 108 + 98 = 300
Total S (Mar, May, June) = 90 + 89 + 91 = 270
Ratio = 300 : 270 = 10 : 9
Rationale: Summed sales for specified months and simplified the ratio by 30.
Difficulty: Easy
Question 3 | Section: QT and DI | ID: 100001
The table given below represents the number of cars sold by four dealers P, Q, R and S in six months of a given year. Based on the given data, answer the question.
The total number of cars sold by dealer P during February to June is what percent (%) more than the total cars sold by all the dealers in June?
| Dealers | P | Q | R | S | Total |
|---|---|---|---|---|---|
| January | 102 | 92 | 95 | 107 | 396 |
| February | 94 | 96 | 104 | 106 | 400 |
| March | 85 | 94 | 100 | 90 | 369 |
| April | 108 | 97 | 99 | 96 | 400 |
| May | 98 | 102 | 100 | 89 | 389 |
| June | 95 | 108 | 102 | 91 | 396 |
Correct Option: 21.2
Solution:
Total P (Feb to June) = 94 + 85 + 108 + 98 + 95 = 480
Total all dealers (June) = 396
Difference = 480 – 396 = 84
Percentage more = (84 / 396) * 100 = 21.21%
Rationale: Comparison of sum of P’s sales vs total June sales.
Difficulty: Moderate
Solution:
Total P (Feb to June) = 94 + 85 + 108 + 98 + 95 = 480
Total all dealers (June) = 396
Difference = 480 – 396 = 84
Percentage more = (84 / 396) * 100 = 21.21%
Rationale: Comparison of sum of P’s sales vs total June sales.
Difficulty: Moderate
